No. 292,024 Claims priority, application JapanJuly 10, 1962 4 Claims. (Cl. 211-) The present invention relates to anovel and improved filing rack for ofiice work cards and the like, andmore particularly to a rotary card filing rack which is simple in theconstruction and by which the filing of office work cards and the likecan be performed with a great efliciency.

Cards have been widely employed in handling ofiice work in order torationalize such work and the employment of such cards has improvedolfice work to substantial extent.

Accordingly, one object of the present invention is to further improvethe handling efficiency of such cards employed for dealing with businessin offices.

Another object of the present invention is to provide an improved ofiicework card filing rack which can fulfil the above object.

Another object of the present invention is to greatly improve theoperative efiiciency of such office work card filing rack byconstructing the filing rack in such a way that the same may rotate andaccommodate office work cards individually and uprightly.

In order to facilitate understanding of the present invention, referencewill now be made to the appended drawings of a preferred specificembodiment of the present invention. Such drawings should not beconstrued as limiting the invention which is properly set forth in theappended claims.

In the drawings:

FIG. 1 is a perspective view of the ofi'ice work card filing rack of thepresent invention.

FIG. 2 is a vertically sectional view of the essential elements of saidfiling rack.

FIG. 3 is a fragmentary top plan view of said filing rack.

With reference to the drawings: The office work card filing rackgenerally comprises a hollow support shaft 1 upwardly and verticallyextending from a base 2 and fixedly secured thereto.

A T-shape section fixture 3 (FIG. 2) is threaded into the inner threadedupper end portion of said support shaft 1. The threaded lower end of amain shaft 4 extends through the fixture 3 into the upper end of thehollow support shaft 1 and is secured therein by means of a lock nut 5with a washer interposed therebetween. Spaced intermediate and lowestrotary members 7 and 8 are loosely mounted around the main shaft 4 inthe longitudinal direction thereof, and the intermediate rotary member 7is provided with a downwardly projecting hub portion 9 whilst the lowestrotary member 8 is provided with an upwardly projecting hub portion 10.A pipe 11, whose inner and outer diameters correspond to those of thehollow support shaft 1, is put on the downwardly and upwardly projectinghub portions 9 and 1t) respectively and fixedly retained there by meansof screws 12. The intermediate rotary member 7 is further provided withan upwardly projecting hub portion 13 and a pipe 14 similar to the pipe11 is put on said hub portion 13 at the lower end of said pipe 14. Theupper end of said pipe 14 is adapted to receive the downwardlyprojecting hub portion 16 of a top rotary member 15 and to be fixedlysecured to said hub portion 16 by means of one set screw 12. The lowestrotary member 8 is supported through a thrust washer 17 by the T-shapesection fixture 3. The outer diameters of the three rotary members 7, Sand 15 are selected so that the top rotary member 15 has the smallestouter diameter, the intermediate rotary member 7 has an outer diametersomewhat larger than that of the top member 15, and the lowest rotarymember has an outer diameter larger than that of any of the respectivetwo upper rotary members.

Each of the intermediate and lowest rotary members 7 and 8 is providedwith three long arm bars 18 and 19 radially extending in the respectivehorizontal directions. The respective upper arm bars 18 are disposedoffset from the respective lower arm bars 19 in such a manner that eacharm bar 19 of the lowest rotary member 8 is disposed just in the middlepoint between the respective two adjacent arm bars 18 of theintermediate rotary member 7 and vice versa. The top rotary member 15and intermediate rotary member 7 are respectively provided with threeshort bars 20 and 21 extending in the respective horizontal directions.The respective short bars 20 and 21 are also disposed offset from eachother in the same manner as described in connection with the long armbars 18 and 19.

An outwardly arched bar 22 connects between the adjacent two short bars20 and 21 and a similarly outwardly arched bar 23 connects between theadjacent two long arm bars 18 and 19. The arrangement of such connectingbars 22 and 23 is such that the opposite ends of each arched bar 22 aresuperimposed on the respective outer ends of the short bars 20 and 21and secured thereto by means of set screws 24 and 24 and the oppositeends of each arched bar 23 are also superimposed on the respective outerends of the long arm bars 18 and 19 and secured thereto by means of setscrews 24 and 24 whereby to form three each sets of V-shape framemembers A and B, the former frame member A being smaller than the latterframe member B.

As seen from FIG. 2, each of the frame members A and B is secured aplurality of multi-angled card backing bars 25 thereto by means ofwelding at a predetermined space so that all of the various backing bars25 may be disposed in a step-like inclined plane, but not in the samehorizon.

With the above construction of the card filing rack by the presentinvention, when folio office work cards P, or thin books or magazinesare inserted between each two adjacent backing bars 25, the verticalinner edge of the cards P leans against the frame member A and thebottom edge of the cards lies upon the frame member B thereby the cardsmay be accommodated with stability. And furthermore, when a plurality ofoffice work cards P are inserted between the respective two backing bars25, since the upper end portion of each card may be exposedly disposed,if any indexing indication is provided on the upper end portion thereof,the cards can be easily identified and picked up whenever particularcards are used, and the insertion of the cards into their proper spacesbetween the backing bars can be also facilitated. Furthermore, since thecard supporting frame members are free to rotate, the user is easilyaccessible to necessary cards without moving about.

It will be understood that the foregoing description in connection witha specific embodiment is only illustrative of the present invention andit is not intended that the invention be limited thereto. Allsubstitutions, alterations and modifications of the present inventionwhich come within the scope of the following claims or to which thepresent invention is readily susceptible without departing from thespirit and scope of this disclosure are considered parts of the presentinvention.

What is claimed is:

l. A card filing rack, comprising a vertical hollow support shaftadapted to be secured to a base or floor; at

least three rotary members mounted on said hollow support shaft in avertically spaced relation to one another, along the length of saidsupport shaft, the top rotary member being provided with three shortbars radially and horizontally extending therefrom, the intermediaterotary member being provided with three long arm bars and three shortbars radially and horizontally extending therefrom, and the lowestrotary member being provided with three long arm bars radially andhorizontally extending therefrom the short bars of the top andintermediate rotary members being connected by outwardly arched barswhich are connected to each other to form upper V-shaped frame members,the long bars of the intermediate and lowest rotary members beingconnected by outwardly arched bars which are connected to each other toform lower V-shaped frame members, a plurality of spaced card backingbars each having one end thereof connected to said upper frame memberand the other end thereof connected to said lower frame member.

2. A card filing rack as set forth in claim 1, in which each of saidupper V-shape frame members is smaller than each of said V-shape lowerframe members.

3. A card filing rack as set forth in claim 1, in which said threerotary members have different outer diameters from one another.

4. A card filing rack as set forth in claim 1, in which the top rotarymember has the smallest diameter, the intermediate rotary member has anouter diameter larger than that of said top rotary member, and thelowest rotary member has an outer diameter larger than those of theother two upper rotary members.
